-Oh shit I'm sorry
-Sorry for what? Our daddy tought us not to be ashamed of our dicks, ‘specially when they are such good size ‘n all. 
-Yeah I can see that, your daddy gave you good advice. 
-It gets bigger when I pull on it. 
-MMHM
-Sometimes, I pull on it so hard, I rip the skin. 
-Well, my daddy taught me a few things too, like how to not rip the skin by using someone else’s mouth, instead of your own hand. 
-Will you show me?
-I’ll be right happy to.
